The inter-cooler pressure, for minimum work required, for a two stage reciprocating air compressor, is given by (where p1 = Intake pressure of air, p2 = Inter-cooler pressure and p3 = Delivery pressure of air)

The inter-cooler pressure, for minimum work required, for a two stage reciprocating air compressor, is given by p_2 = sqrt p_1 p_2 . Where p1 = Intake pressure of air, p2 = Inter-cooler pressure and p3 = Delivery pressure of air.

The inter-cooler pressure, for minimum work required, for a two stage reciprocating air compressor, is given by (where p₁ = Intake pressure of air, p₂ = Inter-cooler pressure and p₃ = Delivery pressure of air)

A) $${{\text{p}}_2} = {{\text{p}}_1} \times {{\text{p}}_3}$$ B) $${{\text{p}}_2} = \frac{{{{\text{p}}_1}}}{{{{\text{p}}_3}}}$$ C) $${{\text{p}}_2} = \sqrt {{{\text{p}}_1} \times {{\text{p}}_2}} $$ D) $${{\text{p}}_2} = \frac{{{{\text{p}}_3}}}{{{{\text{p}}_1}}}$$

Answer & Solution

Correct Answer: Option C

The inter-cooler pressure, for minimum work required, for a two stage reciprocating air compressor, is given by $${{\text{p}}_2} = \sqrt {{{\text{p}}_1} \times {{\text{p}}_2}} .$$
Where p₁ = Intake pressure of air, p₂ = Inter-cooler pressure and p₃ = Delivery pressure of air.

Answer wrong p2=√(p1×p3)

Madhavan Palmani 7 years ago

p2 = sqrt(p1*p3).
